Anna, I wanted to write positively to your posts, procrastinated it though and others took it up. Now I want to reflect to one word, I use differently: *---- MODEL ----* There are several 'models', the mathematical (or simple physical) metaphor of a different subject is one, not to mention the pretty women in fashion-shows. I use *model* in the sense of a reductionist cut from the totality aspect for a topical view: the epitom of which is Occams razor. Observing (studying) a topic within chosen boundaries - limitations of our selection by our interest. Of course Bruno's all encompassing arithmetic system can cover for this, too, but I am not for restricting our discussions to the limitations of the present human mind's potential (even if only in an allowance for what we cannot comprehend or imagine). Beyond Brent's "yam-y" extension. What we don't know or understand or even find possible is not impossible. It is part of 'everything'.
I chose to be vague and scientifically agnostic. Have fun in science John Mikes ** On Fri, Nov 7, 2008 at 7:41 PM, Brent Meeker <[EMAIL PROTECTED]>wrote: > > A.
